H.R. 8634, the Consanguineous Marriage Prohibition Act of 2026, would establish a federal ban on marriage between individuals who are closely related by blood. The bill specifically prohibits marriages between people who are related within the degree of first cousin, meaning that marriages between first cousins and closer relatives would be illegal under federal law. The legislation amends existing marriage provisions in federal law to add this relationship restriction. The bill would affect anyone seeking to marry a close blood relative and would apply nationwide. The proposal was introduced in the House on April 30, 2026, and referred to the Committee on the Judiciary, with no specific funding or implementation timeline specified in the text.
